And it ſhall be a deſolate heap] Heb. an hillock of deſolation.

And her daughters] The neighbour Towns, and Villages.

Then ſhall Iſrael be heir unto them that were his heirs] It hath been often obſerved, that God loveth to retaliate. How this was fulfilled, ſee 1 Macchab. 5.6. and Joſeph. l. 13. c. 21.
